Depending on the hard- and software used to read this text and their settings, not all elements may display as intended. Slightly adjusting the magnification or zoom level may improve the display of overlapping elements.

The page lay-out is loosely based on that in the printed source document, without any attempt at exactly emulating it.

Chapter titles often occur after section titles, which may lead to confusing autogenerated tables of content.

Inconsistencies in spelling, lay-out, use of accents, etc. have been retained; only some minor obvious typographical errors have been corrected silently. Errors in non-English words have not been corrected.
